The DataGridView has something called "virtual mode". Instead of databinding (and the overhead), it simply requests the values that should be on-screen. That means that you can display the first records immediately after loading them. There's a walkthrough[^] on MSDN.

For it to work nicely, you'd load your data on a separate thread, using a reader, and synchronize every now and then (every second or every 100 items).

If so then just set the windowstate property in each form to maximized.

It'd be faster to do this using Notepad++, since the column-title is only present on the first line of the CSV-file. That's also the easiest way to build your project; read the content of the file, replace the word, write it. Take a look at the classes in System.IO.
